We’ve pulled iTweetReply from the iOS App Store because of changes made to Twitter’s API (application programming interface), which caused the problems users have been reporting recently. Unfortunately, the only way to fix this issue is to pull the app and do some tinkering under the hood. As soon as we’re done, we’ll make iTweetReply available at the iOS App Store again, and current users should have their current issues fixed.

Thanks for your patience regarding this matter. We’re also currently working on the Syncode family of apps and will let you know more about their future soon.
